Their is a quicker way to get a result (even if it’s a hobby), inform the Tax office that they are earning an income which they are not declaring to the taxman (a virtual certainty if it’s a cash business).Just for the record the No is 1800 060 062
Income from a “hobby” is not usually taxable. You might have to be able to convince the ATO that it is a hobby, not a part time business. You are not able to claim any deductions against hobby income.
